ID help with spring perches

[Cliff Ramsdell]

Hi all,
I have a pair of spring perches I can't ID. Came with a box of parts, mixed model A stuff with later flathead stuff.

Here's what I can tell, spring over setup so it's till '34 but it's for the thicker axles, 2 1/4" not the 2" as I have a set of '32 hot rod perches.

So, deduction says Model A, Maybe AA but they don't have the bosses for the mechanical brake parts.

Also these have a killer 7 degree angle to then for increased caster and easier steering action at low speeds and easy wheel return and stability.

So..........what do you think and if you have some pics let me know.

Thanks,
Cliff Ramsdell
